To all whom it Imay concern:

Be it known that I, BERNARD F. Roni-nuo,

useful Improvements in Kerosene Incandescent lliamps; and l do herebydeclare the following tc be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

rIhis invention relates to kerosene incandescent lamps. It is desirablein devices of this character to have the mantle centrally supported. Ithas been found that where the mantles are supported from the side, therods or wires supporting them lie so close to the chimney that they tendto crack the chimney when they become highly heated. It .is alsodesirable to have the chimney and mantle removable together from theburner. These mantles are very fragile, and in the devices of thischaracter where it is necessary to separately remove the mantle, saidmantles are frequently broken.

,It is the object of the present invention to provide improved andeconomical means `for accomplishing the foregoing objects.

It is a further object of the invention to provide means for spacing theouter wick tube hereinafter described fron the interior of the sleevefrom which the mantle is supported. The spacing of the wick tube fromthis sleeve provides a passage through said sleeve for the air whichsupports combustion .and-'it has been found the if means are notprovided for preventing it, the chimney is sometimes placed on the lampin such manner that the outer wick tube is not exactly concentric withthe sleeve that surrounds it. This of course gives an unequal flow ofair and produces a ragged flame.

In carrying out my invention I do not wish to be understood'that itshould be confined to the details shown by the accompanying drawings.The inventive idea is roader than the particular embodiment hereinpresented and described, and embraces in construction and mechanism thatwhich comes within the scope of the claims.

With these and other objects in view the invention comprises the novelfeatures of construction and completion of parts hereinafter described.f

D2, holes E and In the accompanying drawings, Figure 1 is a top view ofthe lamp with the chimney and mantle attached; 1Eig. 2 is* a verticalsection of the'lamp cut in two, lon lines l-2 Fig-3 is'a front viewofthe lamp; Fig.` 4 is a perspective of the burner detached and Fig. 5is a detailed perspective view of the flame spreader and mantle support.

Similar letters refer to similar parts throughout the several views, inwhich- A is the lamp-bowl; B is the inner wick tube; C is the wick; D isthe outer Wicktube, provided with flange D1, carrying lugs late F; onplate F is a detachable sleeve, (l, containing openings, Irl, and thesame is operated by band I with knob J; K is the receiver for thechimney, M; L are the pins attached to tube, K; li is the flame-spreaderand mantlerod support ear rying rod N1, said flame-spreader and mantle-rod support carrying arms O, provided rim G1; R is the wickadjustment, which is provided with a collar having a projection I saidcollar is also provided with set screw A U; V is an angular iron madefast tothe top of` ear frame which acts as a stop for the 'A wie W isthedetachable plug set in bowl A pf the lamp for the purpose oi iillingthe Siiid lamp has a bowl of ordinary shape, and is rovided with acentral vertical tube which v1s attached. to the bowl at the lower end,the upper end extending above the outer wick-tube and acting as theinner guide for an annular wick which lits around said tube, and isadapted to'fbe raised and lowered thereon. On the outside of wick is adouble detachable tube D, and on its upper inward portion is constructeda flange D1, for the purpose of changing the-current of air or oxygenthat comes in contact with the iiame, and on said flange are constructedlugs D2, for the purpose of holding the sleeve C that voperates theconical shaped flamespreader and mantle-rod support in a perlect centralposition, so as to produce a per- E for the purpose of allowing an airpassage around its inward portion to keep same cool. At the top isattached 12.` A kerosene incandescent lamp comprising a bowl, an innerwick tube, an outer an annular plate F i wick tube having an out-turnedflange at its that acts as a support for a detachable sleeve upper end,a sleeve surrounding said wick Gr, and prevents an unregulated amount oftube, lugs formed at intervals upon the peair from coming up between theouter wicktube and sleeve Gr. In the outward ortion of sleeve G is arowof openings H an inside of said sleeve is a perforated movableband I,made to correspond with said openings. .I is

a knob attached to the perforated movable f band I, for the purpose ofadjusting said openings in such a way as to allow t ie required amountof air to pass into the burner.

rl'he upper part of sleeve G extends above the wick-tube and is soconstructed as to form an inward projecting flange G2, for the purposeof supporting the conical shaped flames reader and mantle rod support.On' s eeve G, just above the openings in same', is attached a perforatedtube K to receive the chimney M; pins L are attached to said tu be K toprevent the chimney from going beyond said pins, and they also form arestfor said chimney. Immediately above the inner wick-tube B isconstructed a conical shaped flame-spreader and mantle-rod support N,

and having an opening in its lower and central part, which is intendedto receive the mantle rod N1', which supports the mantle in aperfect'centralposition, and which allows the same to hang in a perfectposition overA the flame for the purpose of producing a perfectlyadjusted flame from all sides; on the upwardedge of said conical shapedflamespreader and mantle-rod 'sup ort is constructed ariiis O, whichproject tlierefrom and are rovided with notches P, adapted to fit to tie rim G1, allowing the central mantlesupport and conical shapedflame-spreader, together with the mantle, to be detached from sleeve Crwhen lighting said lamp. In the operating appliance of the wickadjustnient, the wick has an adjustable ear R, and

pinion attached, to be operated y a wheelmade fast to said pinion inconnection with an angular iron attachment V, vwhich is made fast to thetop part of the gear frame, and which is broughtiin contact with aprojection 'l on 'collar S, which has a set screw U, and which allowssaid collarto be 'set at a given point on the vertical shaft, to reventthe wick from being turned too hig thus.
